  • Patent number: 12264229
    Abstract: A resin composition comprising a resin and an aggregated inorganic filler, wherein an increase in a weight of a cured product of the resin composition at 85° C. and 85% RH is 0.80% or less, and wherein a storage modulus of a cured product of the resin composition excluding the inorganic filler at 200° C. is 1.0×107 Pa or more. The resin composition has a high strength and excellent moisture-absorption reflow resistance and reduces the risk of the interfacial detachment being caused by the heat expansion and contraction in the case where the resin composition or the resin cured product is combined with a metal sheet to form a multilayer body.

  • Publication number: 20250033207
    Abstract: A control device of a robot according to the present invention stores a basic file in which the data type of variables for communicating with a PLC is defined. The control device generates, on the basis of the basic file, a definition file in which the data type of the variables is defined in a file format which can be read by the PLC. The control device is formed so as to carry out periodic digital communication for transmitting information pertaining to the variables. The control device allocates, on the basis of the data type of the variables defined in the basic file, areas for variables in an input area and an output area of a memory that is included in a storage unit.
